[0039] In embodiments, the volleyball of the present disclosure has a volume/weight ratio of 21.1 or greater. In specific embodiments, the volleyball has a volume/weight ratio of from 21.1 to about 26.5.

[0040] In embodiments, the volleyball of the present disclosure has a volume/weight ratio of 26.0 or greater. In specific embodiments, the volleyball has a volume/weight ratio of from 26.0 to about 26.5.

[0042] The volume and surface area of the soccer ball, basketball, or volleyball may be calculated according to the general equations for spheres:




where r is the radius.

[0043] The volume and surface area of the football may be calculated according to the general equations for prolate spheroids:




where a is the radius of the short axis, b is the radius of the long axis, and

The radius of the short axis is one-half the length of the short axis, and the radius of the long axis is one-half the length of the long axis. Although a football is not exactly the shape of a prolate spheroid, the difference is not significant.

[0044] The sportsballs meeting the various requirements of the present disclosure are particularly suitable for younger children. The sportsballs are easier to handle, being of reduced weight, and reduce the risk of injury as well. However, the sportsballs can generally also meet the size requirements (i.e. circumference, length) of the various standards described above.

[0045] The sportsballs of the present disclosure are generally made according to known methods in the art. However, certain differences are evident. Cover material will be thinner. Winding layers may be thinner. Lighter weight or less dense materials may be used in the interior of the sportsballs or as cover materials. The bladder and carcass stock may also be thinner. Gases having a density lower than air may also be used to inflate the ball.

[0046] Sportsballs are generally made from a carcass which has a cover layer over it, the cover layer being formed from cover panels attached to the outer surface of the carcass. The outer surface of the carcass may have ribs projecting from it as well to define certain features, such as seams or channels on a basketball. The carcass itself may be formed from an inflatable bladder, a winding layer, and possibly some intermediate layers intended to enhance or reduce various properties of the sportsballs.

[0047] Cover panels generally have a thickness of from 0.5 to 3 millimeters. Bladdders generally have a thickness of from 0.5 to 3 millimeters. Winding layers generally have a thickness of from 0.5 to 3 millimeters. The intermediate layers may have a thickness of from 0.5 to 3 millimeters. Carcasses thus have a thickness of from 0.8 to 5.2 millimeters (ribs are not considered to be part of the carcass for purposes of this measurement).
The sportsball of the present disclosure may have a thinner carcass, such that the ratio of the cover layer thickness to the carcass thickness is 4.0 or greater. In further embodiments, the ratio of the cover layer thickness to the carcass thickness is from 4.0 to about 6.0.
The sportsballs and methods of the present disclosure have been described with reference to exemplary embodiments. Obviously, modifications and alterations will occur to others upon reading and understanding the preceding detailed description. It is intended that the exemplary embodiments be construed as including all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
